This was actually one of the last games that I actually played with any sort of regularity. Just like you, i was disappointed that they reverted to a more "kiddie" graphics style and i found myself lost quite frequently. I know that open-world is all the rage these days but for casual gamers like me that are actually quite busy with work sitting back down and having no idea where I was meant to be going is a fantastic way for me to turn the game off and never play it again.
I guess you could say I liked the game but i kind of tired of memorizing all the songs to change the way the wind was blowing and what not.
